Days now starting to lengthen
It's the winter solstice today.
That's viewed as either the darkest or shortest day of the year.
It also means that the days will start to get longer from now on, even if it's just by a few seconds or minute at a time.
The sun will rise today is at 8.36am and set at 3.56pm - tomorrow (Mon 23) there is a minute longer until the sun dips under the horizon.
